XQuery - RegEx Pattern Matcher

[derstubbi at gmx.de]

Hi,
I am trying to use a RegEx within XQuery. In general that works fine.
Now I have a more complex RegEx to work with CSV-files(these CSV have ";" as separator).
I use can the following without problems in Java :

Pattern Regex = Pattern.compile(
"\\G(?:^|;)(?:\"((?:[^\"]|\"\")*)\"|([^\";]*))");
...

But in XQuery
let $regularExpr :='\\G(?:^|;)(?:\"((?:[^\"]|\"\")*)\"|([^\";]*))'
...
if (matches($row,$regularExpr) ) then ( ...

just gives the error :

Error at character 4 in regular expression "\\G(?:^|;)(?:\"((?:[^\"]|\"\")...": expected ())


I tried the optional flags (i, x, ...) but always with the same result...
What is wrong with this RegEx ?

P.S. :I run the XQuery from Java with Saxon.
